CHIMNEY AND STOVEPIPE ATTACHMENT.

Application filed November 29, 1916. Serial No.

To all whom. it may concern:

Be it known that I, EDWARD C. HENRY, a citizen of the United States,residing at Missoula, in the county of Missoula and State of Montana,have invented certain new and useful Improvements in Chimney andStovepipe Attachments; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to a chimney and stove pipe attachment and hasfor its primary object the provision of means for looking a stove pipein the stove pipe hole of a chimney, preventing the stove pipe fromslipping or withdrawing from the stove pipe hole and obviating thedanger of fires caused by stove pipes becoming detached from chimneys.

Another object of this invention is to provide an element connected to astove pipe and extending through a stove pipe hole of a chimney andengaging the inner wall thereof for holding the pipe against accidentalwithdrawal therefrom.

A further object of this invention is to provide a pair of armsconnected together and detachably secured to the stove pipe and adaptedto extend through the stove pipe hole of the chimney and have their freeends bent at right angles for engagement with the inner wall of thechimney whereby the stove pipe will be held against accidentaldisplacement.

A still further object of this invention is the provision of a chimneyand stove pipe attachment of the above stated character, which shall besimple, durable and eflicient,

and which may be manufactured and sold at a comparatively low cost.

With these and other objects in View, as it will become more apparent asthe description proceeds, the invention consists in certain novelfeatures in construction, combination and arrangement of parts as willbe hereinafter more fully described and claimed' For a completeunderstanding offmy invention, reference may be had to the followingdescription and accompanying drawings, in which:

Fig. 2 is a longitudinal sectional view taken on the line 22 of Fig. 1,

Fig. 3 is an end view looking from the the chimney,

Fig. 4 is a transverse sectional View illustrating the means forsecuring the arms to the stove pipe,

Fig. 5 is a fragmentary elevation of the adjustable securing means for aband surrounding the stove pipe,

Fig. 6 is a detail sectional view of the locking plate and the means forsupporting the same.

Referring in detail to the drawings, the numeral 1 indicates a chimneyhaving a fine 2 with a stove pipe opening 3 in communication therewithfor receiving a stove pipe 1. The stove pipe 4 is of the ordinaryconstruction and to which my invention is applied.

A sectional band 5 consisting of sections 6, 7 and 8 surround the stovepipe as clearly illustrated in Figs. 1 and 2. The sections 6 and 7 aresecured together by a hinge 9 and the section 8 is secured to the otherend of the section 6 by a hinge 10. The free end of the section 7 isbent at right angles to form a bracket 11 which is apertured to receivea threaded rod 12 having a T-shaped head 13 which is pivotally securedto a locking lever 14 as illustrated at 15. The screwthreaded end of therod 12 which extends through the apertured bracket 11 has a nut 16threaded thereon for retaining a spring 17 upon'the rod 12 and whichbears against the bracket 11 as clearly illustrated in Fig. 4:. The freeend of the section 8 is bifurcated as illustrated at 18 forming a pairof relatively spaced arms 19 which are bent to form hooks or curvedbearings. The locking lever 14 has one end thereof bifurcated to form apair of relatively 'spaced arms which are also curved to fit within thehooks or bearings formed by the relatively spaced arms 19 for hingedlysecuring the lever 14. to the section 8 and which will permit the lever14: to be detached from the section 8 when moved into an unlockedposition. When the locking lever 14 isswung to a locking position asillustrated in Fig. 4, the rod 12 extends through the bifurcated end ofthe section 8 and the locking lever and is prevented from any lateralmovement with relation to the sectional band 5. A lock nut 20 isthreaded upon the rod 12 and engages the bracket 11 whereby the tensionupon the spring 17 may be regulated so as to increase and decreaseceived within the stove pipe the clamping action of the sectional band 5upon the stove pipe 4.

From the foregoing description it will be seen that by swinging thelocking lever 14 away from the section 8, the sectional band 5 will beexpanded or enlarged so that the same may be readily slipped over thepipe 4 or the locking lever 1 1 may be detached from the hooks orbearings of the section 8 so that the section 8 may be swung rearwardlyupon the hinge 10 so that the section 5 may be slipped over the stovepipe 4 and by swinging the locking lever 14; in the direction of thesection 8,the section 5 will tightly clamp the stove pipe t, but will beprevented from crushing or mashing the same by the spring 17 upon therod 12 as this spring will permit the rod to move within the bracket 11over a. predetermined pressure of the sectional band 5 upon the stovepipe.

A pair of relatively spaced arms 21 are secured to the sectional band 5and are rehole 3 of the chimney 1 and have their right angles asillustrated at 22 for engagement with the inner wall of the chimney orwithin the flue 2 as clearly illustrated in Fig. 1. The arms 21 areconnected by a substantially semi-circular band 23. A. bolt 24 iscarried by the band 23 and extends through an elongated slot 25 of alocking plate 26 for slidably-securing the locking plate 26 to the band.The locking plate 26 is provided with a plurality of notches 27 whichare adapted to be engaged by an L-shaped plate 28. One of the armportions of the L- shaped plate 28 is forced into engagement with thenotches 27 of the locking plate 28 at all times by a coil spring 29mounted upon ithe bolt 22!: and the other arm portion of the L-shapedplate 28 is adapted to abut the end of the stovepipe for limiting themovement ofthe stove pipe within the stove pipe hole 3 of the chimney 1.The locking plate 26 has its free end bent at right angles to form ahook 30 adapted to engage the outer wall of the chimney 1. By slidingthe plate 26 in the direction of the fine 2 of the chimney 1 until thehook 80 thereon engages the outer wall of the chimney, the arms 21 aretightly clamped to the chimney as the L-shaped plate 28 engages theteeth upon the locking plate :26 preventing longitudinal movement ofsaid plate in the, direction of the stove pipe, thus it will be seenthat the arms are efficiently and permanently secured within the stovepipehole 3 of the chimney, obviating any danger of the stove pipe 1 frombe- Gopies of this patent may be obtained for five cents each, byaddressing the free ends bent ating accidentally withdrawn from thestove pipe opening 3.

If desired, the hook 30 of the locking plate 26 may be provided with anaperture for the purpose of receiving a wire or like element for furthertying the stove pipe to the chimney.

The usual collar 31 is placed about the stove pipe t and in engagementwith the outer wall of the chimney for the purpose of preventing anyescape of the smoke and fumes between the stove pipe and wall of thestove pipe hole 3.

While I have shown and described the preferred embodiment of myinvention, it may be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

1. A chimney and stove pipe attachment comprising a sectional bandconsisting of a fixed section and a pair of movable sections, means forhinging said movable sections to the fixed section, a bracket formed onthe free end of one of said movable sections, a 'T-shaped rod adjustablysecured to said bracket, the free end of the other movable sectionhaving its ends bifurcated and bent to form bearings, and a lockinglever pivoted to the T-shaped rod and engaging the bearings, and meansfor securing the band to a chimney.

2. A. chimney and stove pipe attachment comprising a sectional bandconsisting of a stationary section and a pair of movable sections, meansfor hinging the movable sections to the stationary section, a T-shapedrod slidably secured to the free end of one of said movable sections, acoil spring mounted on said rod and bearing against the free end of oneof said movable sections, the other movable section having a bearingformed on the free end thereof, a locking lever having a bearing formedon one end and resting within the bearing of the second mentionedmovable section and pivoted to the T-shaped rod for clamping the bandupon a stove pipe, and means for connecting the band to a chimney.

In testimony whereof I afiix my signature in presence of two witnesses.

EDWARD C. HENRY.
